Top two pictures are of our second and more extensive geophysical survey over the mostpart of the ridge. Here Justin Yardley, John Bartram and myself are using a British earth-resistance (TR/CIA) system. The results are produced in the black and white image. Although image interpretation training takes around three years to master, if you look at the centre of the picture, a system of interlocking rings (in black) can be seen.
This dark subsurface disturbance represents the barrow ring-ditches which, are not visable above ground. Monument II did not show-up on this image very well although, to the trained eye, we can just makeout this barrow positioned just above the first clear ring-ditch in the upper section of the picture. The reason this feature can not be seen easily is because the chalk cut ring has filled back with the chalk first extracted from it. Our geophysical instruments are therefore, unable to see any back ground variation.
We now suspect one or two further barrows may exist above mound II to the west.
